Below for any one centre position traction substation B (hereinafter referred to as B stations) and its front position traction substation A
(hereinafter referred to as A stations) and rear position traction substation C (hereinafter referred to as C stations), illustrates the two-sided anti-interference protection system of the present invention
Operation principle：
At A, B, C station during normal operation, B Zhan Yue areas disconnecting switch YQS and its auxiliary contact RT1 are in a point position shape
State, the first feed line FC1 at the second feed line FC2 and B stations at A stations carries out two-side feeding, B stations to the first contact net interval CL-1
The second feed line FC2 and C station the first feed line FC1 to the second contact net interval CL-2 progress two-side feeding.Now, first
The switchings of switching input SWITCH1 and second input SWITCH2 is powered off due to RT1 points of position of auxiliary contact, the first switching
The switching inputs of input SWITCH1 and second SWITCH2 state is all 0 so that first group of optical fiber interface that now B stands
Second group of optical fiber interface OPTB at OPTA and A stations is in real-time communication conditions, second group of optical fiber interface OPTB and C station at B stations
First group of optical fiber interface OPTA is in real-time communication conditions so that the now first digital quantity input A_IN at B stations electric signal
The electric signal for outputing the second digital quantity input B_IN at second digital quantity input B_OUT, the A stations at A stations outputs B stations
The second digital quantity input B_IN at the first digital output end A_OUT, B station electric signal outputs first digital quantity at C stations
Output terminals A _ OUT, the first digital quantity input A_IN at C stations electric signal outputs the second digital quantity input B_ at B stations
OUT.So as to：A stand the second feed line FC2 fault-signal can be sent to by optical fiber B stand and output B station the first feed line
On FC1, the fault-signal that B stands on the first feed line FC1 can also be sent to the second feedback that A stands and outputs A stations by optical fiber
On electric wire FC2, B stand the second feed line FC2 fault-signal can be sent to by optical fiber C stand and output C station first feed
On line FC1, the fault-signal that C stands on the first feed line FC1 can also be sent to second that B stood and outputed B stations by optical fiber
On feed line FC2, two-sided anti-interference protective effect is played.
Thus, under the normal operating condition of A, B, C station, the first contact net interval CL-1 and the second contact net interval CL-2's
Two-sided anti-interference is protected and can reliably realized, for example：The a certain position generation event stood as the first contact net interval CL-1 close to A
When hindering and disconnecting feed line FC2 feeder breakers QF so that the second frame leakage protection device K2 at only A stations receives event
Hinder signal, and the first frame leakage protection device K1 at B stations is not when receiving fault-signal, then the interlock tripper at A stations leads to
The the second transmitting terminal TXB for crossing second group of optical fiber interface OPTB sends fault-signal to first group of the interlock tripper that B stands
Fault-signal is outputed to the first feedback by the first digital output end A_OUT after optical fiber interface OPTA the first receiving terminal RXA
Electric wire FC1 feeder breaker QF so that relay QF is acted and disconnected.
When being run in A, B, C Zhan Yue areas, the first feed line FC1 and the second feed line FC2 at B stations are out of service, and what B stood gets over
Area disconnecting switch YQS and its auxiliary contact RT1 are in closing position state, first feed at the second feed line FC2 and C stations at A stations
The combination interval that line FC1 is linked to be to contact net interval CL-1 and contact net interval CL-2 carries out big two-side feeding.Now, B stands
The the first switching input SWITCH1 and the second switching input SWITCH2 of interlock tripper close position due to auxiliary contact RT1
And obtain electric, now the first switching input SWITCH1 and the second switching input SWITCH2 state are all 1 so that B stations
First group of optical fiber interface OPTA of interlock tripper and second group of optical fiber interface OPTB formation internal communication, i.e. it is bilateral that A stands
Second group of optical fiber interface OPTB of shunt tripping device the second transmitting terminal TXB and the second receiving terminal RXB is respectively turned on the bilateral of C stations
Jump first group of optical fiber interface OPTA of device the first receiving terminal RXA and the first transmitting terminal TXA so that now the second of A stations counts
Word amount input B_IN electric signal outputs the first digital output end A_OUT at C stations, the first digital quantity input at C stations
A_IN electric signal outputs the second digital quantity input B_OUT at A stations.So as to：The second feed line FC2 of A stations fault-signal
C can be transferred directly to by optical fiber to stand and output on the first feed line FC1 of C stations, and the event on the first feed line FC1 of C stations
Barrier signal can also be transferred directly to A by optical fiber and stand and output on the second feed line FC2 at A stations, play big two-sided anti-interference
Protective effect.
Thus, under A, B, C Zhan Yue areas running status, the first contact net interval CL-1 and the second contact net interval CL-2's
Two-sided anti-interference is protected and can equally be able to reliably realize, its real process is similar with the implementation process under above-mentioned normal condition,
This is repeated no more.
The present invention is not limited to above-mentioned embodiment, according to the above, according to the ordinary technical knowledge of this area
And customary means, under the premise of above-mentioned basic fundamental thought of the invention is not departed from, the present invention can also make other diversified forms
Equivalent modifications, replace or change, all fall among protection scope of the present invention.
